ADJUSTABLE BEARING.

Application filed December 18, 1925. Serial No; 76,253.

This invention relates to improvements in adjustable bearings moreparticularly, although not solely adapted for use with power shears.

In the use of power shears as ordinarily constructed it has been foundthat the bearing on the movable cutter member side of the shears wearsout within a short time, due

to the torsional strain, with the result that the cutting edge of themovable member under strain of cutting will tilt away from the fixedcutting member and will not make a clean cut and further will requiremore power in cutting. i

It is one of the objects of the present invention to overcome the beforementioned objectionable features and provide an adju-stable bearingwhich will take up the With the above and other objects in view.

the invention consists of the improved adjustable bearings and its partsand combinations as set forth in theclaims, and all equivalents thereof.

In the accompanying drawing in which the same reference charactersindicate the 1 same parts in all of theviews:

Fig.1 a side view of a portion of a power shears provided withtheinipro'ved adjustable bearing;

Fig. 2 is a vertical sectionalv view thereof taken on line 2-2 of Fig.1;

Fig. 3 is a fragmentary top view of the bearing; a i r Fig. 4 is a frontviewof one of the bearing parts; r l

Fig. 5 is an edge view of the part shown in Fig. 4;

Fig. dis a side view of another bearing part; and j r Fig. 7 is a sideview of the rear bearing. Referring to thedrawing the numeral 8indicates a portion of the frame or support of a power shears of thetype commonly known as alligator shears having a fixed lower cuttingedge 9 and a U-shaped portion 10 forming bearings 11 and 12 throughwhich the shaft 13 extends. The upper movable element on cutting member14; is formed with a cutting edgelo, a medial hub portion 16 extendingbetween the bearing portions 11 and 12 and a rearwardly extendingportion 17 which is engaged by the power means (not shown) for operatingthe movable member. The'cutting edge 15 coacts with the fixed cuttingedge 9 and the shaft 13 extends through the medial hub portion 16 and isrigidly connected thereto so that the turning movement is between theshaft and the bearing portions of the support 8. A hearing member 17having an angular lower face 17 is adjustably connected to thebearingmember 11 by a stud screw 18 and said member 17 supports the end portionof the shaft extending through said member 1 1 and due to its lowerangular face 17 is adjustable to take up wear.

A circular bearing member 1.8 surround ing the shaft 13 and interposedbetween the hub portion 14 and the bearing 12, isformed with an annulargroove 19 on one side. radial cross grooves 20 on both sides andtransverse connecting ports 21 for lubricating said bearing member 18.Due to the torsional strain between the shearing side of the hub 16 andthe bearing 11 considerable wear is caused between said parts and tocompensate for this wear the inner-surface of the bearing 16is angled asindicated by the numeral 22 to receive the angular outer face 23 of awedge member 21. Said wedge member is of bifurcated formation so thatits'legs 24 will extend on opposite sides of the shaft 13 and the upperportion of the member is provided with outwardly extending slotted lugs25 for receiving stud screws 26 which are mounted in the upper endportion of thebearing 11. Nuts 27 threaded on the studs and positionedabove and below the lugs 25 provide for adjusting the position of thewedge member to compensate for wear. A bearingmember 28 somewhat similarto the bearing member 18 surrounds the shaft 13 and is interposedbetweenthe wedge member 24 and the adjacent side portion of the hub 16. Thebearing member 28 is provided with outwardly extending uide side fl ges29 which enter amu e edge elongated recesses or grooves 30 to form aguide for said wedge member and to prevent turning of the bearingmemberQS, the wedge member being also heldin position by the stud screws26. L

The Wedge member 24: is formed with oil holes and grooves 31 and thebearing'niember 28 is also provided with oil grooves and openings 32 tolubricate the bearing surfaces of ,the parts.

From ,t-he foregoing dcscniption, it will be seen that the partscan ;beeasily adjusted to take up wear so that the shearing edge ofthe movablecutter jlllOIIlbQl' may be maintail ied in proper position with relationto the fixed cutting member ,to do efiicient Wonk.
